Anyone with an EpiPen prescription can get a maximum of $100 off their insurance co-pay fee when purchasing an EpiPen or EpiPen Jr. 2-Pak.

To take advantage of the offer, simply request the card from your doctor’s office or by calling 1-800-395-3376. See more details at the website epipen.com. Bring the co-pay card to your pharmacist along with your EpiPen prescription.

The co-pay card may be used on up to three 2-Paks per prescription, or may be applied to an unlimited number of prescriptions. The promotion ends at the end of 2014.

The co-pay card is available to most insured patients, with the exception of those insured by federal or state health-care plans. The offer is not available outside the United States.
